Cosmetic Spiral Pins from the 550 SERIES - SPIRAL SPRING PINS

The spiral pin from the 550 series has been specifically designed for cosmetic housings to ensure a perfect balance between strength and flexibility. The 1-1/2 coil construction guarantees that the cosmetic spiral pin exerts sufficient radial force to achieve the desired torque over the long term, while protecting the plastic from excessive stress. Using the SPIROL 550 series cosmetic spiral pin will simplify your design and manufacturing process. A uniform radial spring force allows for controlled hinge movement and ensures consistent hinge quality over time. The controlled movement of the hinge is achieved with wider tolerances and lower molding costs compared to using a solid pin or cut wire. Finally, the low insertion force and compression of the pin during installation minimize stress and strain.
